A: Mike had found the drive into town from the airport most interesting. "So many changes," he said. "And now I suppose your children are pretty well grown up. They were all teenagers when I saw them three years ago."

B: Marge took a couple of limes from the bin. "And I'd like half a dozen mangoes," she said.

Clem shook his head. "We don't have that many left," he told her. "Your cousin Jane took a third of what I had plus two thirds of a mango. Then the doctor took a third of the rest plus two thirds of a mango, and Betty Butt was in just now and she took a third of what he left. You can have what remains."

How many would that be?
